Humans risk extinction without offworld migration, author warns

A new book by Henry Gee argues that humans face extinction within the next 10,000 years unless they migrate off Earth. He emphasizes that this is a natural cycle for species, not just due to catastrophic events. Gee highlights that humans are poorly equipped to handle diseases and environmental changes. He notes that our population has always been small and vulnerable, despite our recent global spread. The book also discusses the impact of agriculture on human health and the importance of a large population for technological advancement.
